...These are called reverse micelles, and reverse micelles can solubilize water inside them. The term micelle was coined in 1858 by Karl Wilhelm von Nägeli (1817-91), who suggested that starch and cellulose gels exhibit optical anisotropy because they have a microcrystalline structure in which the molecules are oriented, and called this structure a micelle. Later, it became clear that cellulose and other molecules are not aggregates of small molecules, but macromolecules, and the tufted micellar theory, which states that cellulose polymer chains partially aggregate to form bundles and become microcrystals, became widely accepted. *Some of the terminology explanations that mention "Nägeli, KWvon" are listed below.

…これを逆ミセルといい,逆ミセルはその内部に水を可溶化することができる。ミセルという言葉は,1858年ネーゲリKarl Wilhelm von Nägeli(1817‐91)が,デンプンやセルロースのゲルが光学的異方性を示すのは,分子が配向した微結晶構造をもつためと考え,この構造をミセルと呼んだのが始まりである。その後,セルロースなどは小分子の会合体ではなく,巨大分子であることが明らかになり,セルロースの高分子鎖が部分的に会合して束をつくり微結晶になるという,ふさ状ミセル説が広く行われるようになった。… ※「Nägeli,K.W.von」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
